Holes and Depressions: Look Deeper with Shadow-Free Illumination

Born out of necessity from surgical microscopy, near vertical illumination allows for observation into deep bored holes and recesses.

Now you don’t have to resort to surgical microscopes to benefit from this feature. The Leica LED5000 NVI and LED3000 NVI are attachments that integrate two powerful LEDs along the optical path. Anything from cartridge cases, to cylinder heads, and injectors can be viewed with shadow-free illumination.

This is a modular accessory that fits on all high end stereo microscopes. Even with the small distance between the sample and the objective, the Leica LED5000 NVI still offers a shadow-free result. If you have an M-series stereo microscope then you’ll want to go with the Leica LED3000 NVI.

“Users preferring a different color temperature can put any commercially available filter into the integrated filter insert,” said Matthias Schacht, product manager. “This is useful for generating the light characteristics of a halogen light source, for instance.”

This is also useful for reducing reflections when looking at metals or other shiny surfaces.

Shadow-free illumination is useful in those very specific situations, but it’s better to be prepared for any kind of sample.

Don’t be left in the dark.
